Description

Pre Box S2 Digital marks a new era for our S-series components. For the very first time, we are using a dual mono configuration with the highest class D/A converters of ESS Sabre, their flagship DAC chip ensures the audiophile-grade sound in a small and affordable package. This DAC is capable of high-resolution audio up to 32bit 768kHz PCM and DSD512! Pre Box S2 Digital is also the very first of our devices to support hardware MQA unfolding via USB. It’s also the premiere of our proprietary Optimum transient digital filter and our proprietary clock circuitry design. Digital audio is the art of time, with the new proprietary clock design we have managed jitter rates of unrivaled 100 Femtoseconds, this easily outperforms many renowned and respected audiophile clock generators! With organic polymer capacitors and thin-film mini-MELF resistors, we were able to create a tiny device that will blow away even much bigger components for a much higher price. With a total of seven digital filters, the sound can be shaped precisely to the listener’s liking. Pre Box S2 Digital is can also control the playback software of a computer. You can use Play, Pause, Forward, and Rewind straight with your Pre Box S2 Digital!
